The SSP2 shapes, fills and seals blister strips and allows an introduction into fully-automatic production. Filling can be done alternately either via roller dosage to partially fill cavities or via diaphragm dosing for complete filling. The blister packaging can be customized as wound double strips or sheared single strips, mounted by down-stream machines and then finally packaged.
SSP2 is a DPI machine designed to manufacture dry powder blisters in small batch standard.
A drum filler is used for micro-dosing dry powder in this SSP2.
The filled blister webs are cut into strips while still in the machine.
The blister strips are wound up for further processing later. It goes without saying that the filled blisters are handled with care.
Minimum quantities of active-ingredient powder are dosed into blister cavities for dry powder inhalers. Plastic forming of these tiny cavities is achieved through thermal forming (PE film) or cold forming (aluminum film).
The powder filling module that is completely integrated into the machine can be optionally equipped with a drum filler or with a diaphragm filler. For roller dosing, the cavities are partially filled, for diaphragm dosing, the blister cups are filled up to 100%.
Filled blisters are closed with covering or forming film. The sealing tools used can be configured by adjusting pressure, temperature and time separately for each material.
